Permalink链接有什么作用？ [英] What does Permalink link do?

问题描述

邮件底部的永久链接链接是什么？它是做什么的？

解决方案

根据维基百科

Quote：

永久链接（永久链接的portmanteau）是一个URL，指向从首页传递到存档后的特定博客或论坛条目。因为固定链接无限期地保持不变，所以它不易受链接腐烂的影响。

所以我认为这里也有相同的概念。

当网站内容是动态的时，您仍然可以引用其网址，但它们可能会在将来消失并变为无效。永久链接是保证在以后随时指向相同逻辑资源的URI，即使站点和此资源本身发生更改。

What is the "Permalink" link at the bottom of messages? What does it do?

解决方案

According to wikipedia

Quote:

A permalink (portmanteau of permanent link) is a URL that points to a specific blog or forum entry after it has passed from the front page to the archives. Because a permalink remains unchanged indefinitely, it is less susceptible to link rot.

So I think its the same concept here as well.

When the site content is dynamic, you still can reference its URLs, but they may disappear and become invalid in future. A permalink is the URI which is guaranteed to point to the same logical resource any time later, even if the site and this resource itself changes.
